To all whom it may concern:

Be it known that we, G nouon HENRY Fonnns'rnie, a subject of the King of Great Britain, residing at Rieinore, Iver, in the county of Buckingham, England, and GIL- nnn'r lVlansr-r, a subject of the King of Great Britain, residing at 33 Savile Row, London, England, and the said G-ILnnn'r MARSH, acting in his capacity of administrator of the estate of JOHN Daumne'ron Marten, a subject of the King of Great Britailnand formerly a resident of 33 Savile Row, Lon don, England, aforesaid, who died on the 21st day of March, 1919, have inventedcer tain new and useful Improvements in Ap paratus for Building Concrete Structures, of which the following is a specification.

This invention relates to improved apparatus for building concrete structures consisting of an inner and an outer frame constructed of sections of metal sheeting.

According to this invention each section consists of a plate of corrugated iron faced with a steel plate. The two plates are riveted or welded together, the corrugated. iron plates of adjacent sections overlapping one another. The sections are held together by longitudinal bars and secured at the desired. distance apart by bolts. To form the angles of the structure, angle pieces are provided. which are secured to the end sections of the frames. To provide openings for fireplaces and doors, frames of the required shape are inserted between the inner and outer frames, and openings for windows are similarly made except that the window frames are not inserted until the concrete between the inner and outer frames has reached the required height. When the inner and outer frames have been erected concrete is run in between them, but before it is thoroughly set the bolts joining together the frames are turned in order that they may be easily withdrawn afterward.

In order to facilitate the drying of the walls pipes leading from the top to the bottom of the walls are inserted between the inner and outer frames before the concrete is filled in.

When the concrete is set the frames can be easily dismantled by withdrawing the bolts. and removing the longitudinal bars.

The annexed drawings illustrate ap paratus made in accordance with this invention. Figure 1 is a horizontal section. Flg. 2 is a longitudinal vertical section showing a door and window opening. Fig. 3 is a vertical section through a window opening. Fig. 4 is a plan of two plates piaced in position and connected together. Figs. 5 and 6 are elevations of the two plates-shown in Fig. l looking in the direction of the arrow. Figs. 7 and 8 are plans of angular sections used at the corners of the structure, Fig. 7 be1ng an outside section and Fig. 8 an inside section. Fig. 9 shows a plan of a building. Fig. 10 shows a form of clip which may be used and indicates how it is applied to the plates.

Sections 10 consisting of steel plates 10]. and corrugated plates 102 are welded together, part. of the corrugated plates 102 extending beyond the plates 101 as shown at 103 (Fig. 4). When the plates are in position, the corrugated plate on one sec-- tion overlaps the corrugated plate on the adjacent section and they are secured together by clips 104. The sections 10 are erected to form the walls of a structure and are held together by longitudinal bars 11 and bolts 12 which pass through the bars and are secured by nuts 121. At the corners of the structure angular sections 13 are used as shown in Figs. 1, 7 and 8. The corrugated plates 102 of the sections 10 overlapthe corrugated plates 131 of the sections 13. the corrugated plates being secured together by clips 132.

When making a block for a chimney, the sections are as shown in Fig. it marked 14;, 14, the corrugated plates 14.1 of the sections 14 being secured to the plates 102 by clips 142. A pipe 15 is placed in the concrete of the corner to form the chimney. Pipes 16 are also insertedin the walls to accelerate the drying of the con rete. When the concrete is set the pipes are removed.

Referring to Fig. 2, to form a door opening the frame 17 is placed in. position between the platcs on the foundation 18. and to form a window opening a frame 19 is inserted between the plates after the concrete has been run in t the desired height.

7 To make a. structure as shown in Fig. 9, the plates or sections are erected as set forth above to form outer walls 20. inner walls 21 having doors 22 and windows 23; the inner and outer Walls and the door frames 17 may all be erected before the concrete is run in and when it is set the sections are removed, and may be used to form a second story by being similarly placed at the top of the walls of the structure already formed.

The plates 101 may be plain or embossed with any design; in some cases. the concrete may be so embossed as to resemble stone. In Fig. 10 we have shown a clip 10% which may be used and which is indicated in other figures of the drawing.

What we claim is 1. Apparatus for building concrete structures comprising sections of metal sheeting consisting of corrugated iron plates faced with steel plates, the corrugated iron plates of adjacent sections overlapping one another, and means for securing the overlapping plates together.

'2. Apparatus for building concrete structures comprising sections of metal sheeting consisting of corrugated iron plates faced with steel plates, the corrugated iron plates of ad1acent sections overlappmg one anther, corner pieces of corrugated iron plates faced with steel plates and means for securing the overlapping plates and the corner pieces together.

3. Apparatus for building concrete structures comprising sections of metal sheeting consisting of corrugated iron plates faced with steel plates, the corrugated iron plates of adjacent sections overlapping one another, means for securing the overlapping plates together and longitudinal bars and transverse bolts adapted to hold the sections together.
